It's a good idea to buy coins in fractional values. I purchased Krugerrands back when everyone was divesting their South African investments. Picked up coins in 1/10, 1/4, 1/2 and full ounce weights. I paid scrap value of $420 to $450 per ounce in 1983. I had changed jobs and had about $10k in a retirement program pay out I needed to invest. Many dealers had the coins in small lots at that time.
